and State of Colorado, have invented certain new and usefulImgrovementsin Compensating Gear, of whic the following is aspamfication.

This invention relates to corn ting gear of the type shown in my UnitedStates atent #845,409 issued to me February-26, 1907.

The present invention has for its objects among others to improve andsimplify the construction as well as to increase the eflicicrzey in oration. The eccentrics are fasten toge erinpairswhicharecontrollcd bylinks which latter are togather in he. These pairs sltemate, that istosay, e gair oflinksnever engages pair of eccentrics, u]; one edge ofopposite pairs of-eccentncs. v

The present construction is adapted bffi w gear, and procatory motioninto a rotarymotionwithout anydcad center.

Other'ob ects and .of theinvention will hereinafter appear and the novelfeatures thereof will be partiwlarly out in the appended claims.

The invention is clearly of this specifics tion and in'whiht higure I isa side elevation partly in secnon of a com pcnsating g'ear constmcted inacconlance with the resent invention, the secfionbeingasontelinel-l ofllig. 2. Fig.2isasectionontheline22cf 1g. 1

Referring to the drawing, 1 dtes a driving element which may he in thenature of a. hollow disk-shaped casing, as shown in Fig. 1 and asillustrated in my prior patent above referred to. But it may assume anyother foam, as, for instanfce, twgy 13118 2 and 3 arrange at an 0 nineegress, as seen-m Fig. 1. driving element, of which either form may beemployed, is de- BIFDBd to be rotated from any suitable source 0 power(not shown) so as to transmit its mtpsnymg drawmgs' which? the m g k W1nu-' morals of reference marked thereon, f m a.

i motion to the driven element soon to be described. The driving element1 is formed j with elongated slots 4 and 5 which instead of being formeddiametrically opposite each other, as in my prior patent, are arrangedat an angle of ninety degrees to each other as seen in Fig. 1. In theseslots are moun slide pins or bolts 6 and 7 res ctively. The drivenelements 8 an 9 are referably in the nature ofoppositely extensingindependent shafts having their inner ends arranged in close roximity toeach other, as seen in Fig. 2. %'hey are suitably mounted in' or thelike 10 extending from op- 'tesides of the casing, or arms, as seen inFig. 2. These driven elements 8 and 9' in one embodiment of the presentinvention may be connected with the drive wheels of a motor vehicle, sothat said wheels will be individually driven from the driving element 1in such a. manner that they can rotate at different in turning curves.

While m the prwent instance I have chosen to show but one pair ofeccentrics on each shit and as'many pairs of links, it is to be herenoted that there may be more than one air of eccentrics and a co ndingnum r of links for each shaft, although the number shown is deemed mosteflicicnt for o F urpose s.

Each 0 the dnven elements 8 and 9 inside the casing or the equivalentthereof formed the parallelarms 2 and 3 of-the driving ement'1s-provided withtwo eccentrics ll and'I-Z-and l3 and14 'vely'. Theeccentric 11 is connected by link lfiwith the in or boltfi and theeccentric 12 is connected y link 16 with a pin or bolt 7. Theeccentric-l3 is connected by link 17 with the pin or bolt 6 and theeccentric 14 is connected by link 18 with the in or bolt 7, all as shownbest in Fig. 2. t will be understood that each of the links is formed atits inner end with a large e c or the like 19 to embrace the eccentric eat the outer and each link 18 formed with a small eye 20 to surround thesliding pin or bolt with whihh it is connected, as seen clearly in 1.

As seen best in Flg. 2 the links are formed with 22, those on theoutside links exten inwardly only, and those on the inside extendingoutwardly onl these bosses serve as spacing devices to cop the links inparallelism, the agf'gcent ends of the on the outside 11 abutting. By
